IMPROVEMENTIN WIN'DOW-SHADES.

The Schedule referred to in these LettersAP-atent and making part of the same.

To allewhom 'it may conce-r11:

ABe it known thatI, ANsnL W. Fortran, of Union City, inthe county o i' Randolph and inthe State of Indiana, have invented certain new and useful Iin'-,` lprrovenients in Window-Shades; i and do hereby declarc' that'the following. is a full, clear, and exact'description thereof, reference beinghad-to the accompany-y ing drawing and to'thefletters'of reference marked thereon making a -part of this specification. 'Thefnature of my invention consists in. the construct-ion and arrangement of a window-shade, which eanbe raised from the bottom or lowered from the top at will, as will be hereinafter more fully set forth.

*Inv order to enable others skilled in the art to whichV myinvention appertains to make and use the same, I' will now proceed to describe its construction and operation, referring to the annexed drawing, in

Figure l is a front view, showing the shade entirely covering the window;

Figure 2 is a similar view, showing the shade lowered from the top Figure 3 is also a front view, showing the kshade raised from the bottom; and

Figure 4is a transverse vertical section through lo thepper ends of the'flanged end-pieces ee aref attached cords, fj, which pass upward over pulleys, 71. h, in the upper part of the window-frame, said cords being afterward connected together. f

` Other cords, f'f, are attached to the ends of the uppermost slat a, and pass over pulleys, h 71.', placed immediately in rear of the pulleys h h.

These cords are also connected together, and, being hooked onto a pin or hook, i, on the side of the Window-frame, hold the entire shade up to the top Aof the Window, as shown in fig. 1. By iooseningthe cords f' f' from the hook t, the shade maybe lowered from the top so as to admitlight from the top of the window, and and also admit air, if the upper sash isA lowered, as shown in fig. 2.

By the use of the cords f f the shade can be raised from the bottom to any height desired.

It is, of course, understood that one or more suit able hooks or pins must be provided, to which the which 'reason I cords f orf are to be attached, for holding the shade in any desired position.

In cithe1"case,.whether the shade is lowered from' the top or raised from the bottom, the slats fold into the vbox d c, and the movement in either direction can be'executed vwith the utmost rapidity without danger A of entangling, or in any way injuring the slats.

In place ot' pins or hooks for fastening the cords, I,may providea spring at any suitable point on the window-frame, underl which the cords may be slipped and helds as to support the shade at any height'desired.

The shade need not necessarily be made to cover the entire window. It may be made in sections, each section covering a portionof thev wind'o\v,.and provided With its own rigging, sofas to operate independently of the other, thus dispensing with the expensive inside shuttelrs.

For the proper working of my shade it is necessa ry to connect the Vslats in a peculiar and particular manner, which is as follows:

The low-'er edge of eacli slat overlaps the .upper edge of the slat immediately below it, and the straps I are attachedlto thc slats near their upper edges.' 'In' inch-slats the straps should be attached about oneeighth of an inch from the upper edge.

When the slats Yare arranged and connected in this manner they will fold up very readily' as a book, for

have given it the name of a book- A shade.

Having' thus fully described my invention, 'What I claim as new, and desire to secure by Ilet- ,1; .A window-shade, composed of slats connected by straps or equivalents, when said straps are attached to the slatsnear the upper edge, and the lower edge of each s latoverlaps the upper edge of the I adjoining slat, substantially as herein sct'forth.

2. In combination with a window-shade composed:

of slats and straps, or equivalents, in the manner described, the boxd e,.constructed and arranged sub'- stantially as and for the purposes herein set forth.

3. VThe within-described book-shade, constructed as described, so as to be lowered from the top, and aised'from the bottom at'will, substantially as set Orth.

In testimony that I'claim the foregoing I have hereunto set my hand this 22d day of December, 1870..

ANSEL W. PORTER.
